Problems solved by technology

Although this type of method can detect that the object is in an unsafe area before the collision, and can judge the movement of the object, the image processing algorithm is complex, and the performance requirements of the entire protection system are relatively high; and the image is in the two-dimensional category, in the actual detection Cannot accurately judge moving objects in three-dimensional space, and is easily disturbed by external factors

Embodiment Construction

[0047] Such as figure 1 As shown, the protection device of the escalator of the present invention includes a protection box 1, and the protection box 1 is a hollow box-shaped structure composed of a protection plate and a side plate, and is installed at the angle between the escalator and the floor slab 9 or the triangular area between two intersecting escalators;

[0048] Such as figure 2 As shown, a photoelectric sensor 2, a signal processing device 3, and a voice broadcast device 4 are fixedly installed in the protective box 1, and the photoelectric sensor 2 is installed on the protective plate for collecting signals and transmitting them to the signal processing device 3; It is used to process the signal sent by the photoelectric sensor 2, and send an instruction to the escalator control system according to the judgment result to make the escalator stop slowly or suddenly; Voice broadcast device 4 can play the effect of warning when passenger 7 is in non-safe area, when s...

Abstract

The invention discloses a protection device of an escalator. The protection device comprises a protection box, and a photoelectric sensor and a signal processing device are fixedly arranged in the protection box; the photoelectric sensor collects signals and transmits the signals to the signal processing device; and the signal processing device processes the signals sent by the photoelectric sensor, and according to a processing result, an instruction is sent to an escalator control system, so that the escalator is slowly stopped or urgently stopped. According to the invention, it can be ensured that before injury accidents happen, passengers with risks of the crushing injury can be accurately detected; and according to the positions where the passengers are located, the voice prompt or the stopping is selected, so that the protection effect is achieved.

Description

technical field [0001] The invention relates to an accessory of an escalator, in particular to a protective device for the escalator. Background technique [0002] During the use of the escalator, passengers (especially children) lean out of the handrail due to negligence, and move with the escalator to the angle between the escalator and the floor or the angle formed by two intersecting escalators place, very prone to pinching injury accidents. Once such an accident occurs, immeasurable losses will be generated no matter for the injured passengers, the escalator management party or the escalator manufacturer. [0003] Section A.2.4 of the newly promulgated GB16899-2011 "Safety Specifications for the Manufacture and Installation of Escalators and Moving Walks" stipulates that at the intersection with the floor and between the escalators or moving walks set at each intersection, the handrail should be set A vertical protective baffle without sharp edges shall have a height ...
